I was recently in the bathroom, brushing teeth (tooth), trimming beard, and doing general maintenance work, when I looked into the mirror behind the hand basin, and saw a glimpse of myself in the guise of my Great Grandfather; above.
It was quite a shock as I suddenly, for the first time, saw any resemblance between myself and my ancestor. It isn't easy to see beyond his large bushy beard; even though I have a trimmed version myself.
Of course, there are bound to be physical similarities along the same blood line. I certainly see it in my own children, and in their own children, but I hadn't previously seen any particular resemblance to my own spear-side relatives. In fact I look much more like my mother than my father.
It was a slightly perturbing, if reassuring, experience; albeit very fleeting.
A wonderful thing heredity.
